  • Overwrite detection diagnostic for memory heap
    Patent number: 7434020
    Abstract: A data structure within a block of allocable memory of a memory structure such as a heap is used to store an overwrite detection pattern. When memory is passed back to the operation system for any reason (typically freeing the memory, reallocating a larger/smaller buffer, or querying the size of the allocation), the overwrite detection pattern is usually checked. If the overwrite pattern has been modified, an access violation can be forced.

  • Dynamic memory heap tagging
    Patent number: 7350045
    Abstract: A data structure within a block of allocable memory of a memory structure such as a heap is used to identify the function that is responsible for causing memory problems such as random overwrites, buffer overruns, double or multiple “frees,” and the like. The data structure can use the return address of the function that allocates or frees the allocable memory block to identify the caller. An identifier for the function is generated and stored in the allocable memory block.
